Initial analysis

The two-unit residential building at 85 Valparaiso St in Russian Hill, owned by Stanley Wong, is a two-story flats and duplex structure built in 1907. The most significant recent improvement to the property occurred in 2017, when comprehensive remodeling work was completed on both units at a cost of $120,000. This renovation included the remodeling of two bathrooms and two kitchens, installation of new plumbing fixtures throughout the building including bathtubs, toilets, vanities, kitchen sinks, ranges, water heaters, washers, and dryers, as well as an electrical upgrade featuring new lighting, switches, receptacles, a fan, dishwasher, and smoke detectors. The building's maintenance history shows earlier improvements including aluminum window installation in 1989, though records indicate a reroofing permit from 1996 that is marked as expired.

The property has experienced several parking-related incidents in the vicinity, particularly in 2021-2022, with multiple reports of abandoned motorcycles/scooters and illegal parking, though most of these cases were resolved with no permanent issues noted. A construction equipment blocking incident was reported and resolved in March 2022, and there was a street cleaning issue involving loose garbage in February 2020. Of note, there was one carbon monoxide detector activation incident recorded, though no actual carbon monoxide was detected and no injuries were reported. The building's maintenance record demonstrates regular upkeep through permitted renovations, with no indication of unresolved maintenance or safety issues at this time.

Risk rating

How 85 Valparaiso St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
86th percentile

Out of 1133 buildings in this neighborhood, 159 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 81.8%
Moderate concern 9.5%
Severe concern 8.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
